Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.

Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.

Description:
These Duro inner tubes come in several widths
and Diameters and in 1 valve length, 33mm. The varying widths and diameters are super accommodating. These inner tubes can be used to tire widths between 1.0� 1.5� & 2.1� 2.4�. That�s ...

These are the lightest tubes you can use for your fatbike 3.8-4" tires. Be warned however, running lower pressures may result in pinch flats. These baby's are S T R E T C H E D way out there in a 4" tire so patching one usually doesn't work well. This is the lightest alternative other than tubeless.

If you use your mountain bike on the street then these tubes are fabulous. Most thin mountain tubes have stems designed for deep V section rims. I do not have deep V rims so these shorter threaded and nutted stems work a lot better. Dealing with Jenson is always a pleasure.
